Subject: mm: call {ptlock,pgtable}_cache_init() directly from mm_core_init()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=4cd1e9edf60efb20fad35cf5e9ade7ad75b34cd1;p=linux.git

mm: call {ptlock,pgtable}_cache_init() directly from mm_core_init()

and drop pgtable_init() as it has no real value and its name is
misleading.
